Abstract
A switch module for an electronic device detects translational inputs and defines at least portion of a conductive path from an input surface of the electronic device to a processing unit of the electronic device. The switch module may be a component of a crown assembly for detecting rotational inputs, translational inputs, touch inputs and/or biological signals such as electrocardiogram (ECG) signals. The switch module may include a conductive dome and a friction guard that is positioned between the conductive dome and the actuation member of the crown assembly. The conductive dome and/or the friction guard may define at least a portion of the conductive path from the input surface to the processing unit.
